论文摘要
在本文中，我们建议如何为BB84量子键分布（QKD）协议构建对帐方法。从理论上讲，它是无条件安全的，因为它基于物理的量子定律，而不是数学问题的计算复杂性。 BB84协议性能可以通过各种错误和信息泄漏来降低，例如协议的内在效率有限，设备不完美和窃听。提出的对帐方法允许使用涡轮代码清除这些错误。由于它们的高误差校正能力意味着获得较低的错误，因此该方法具有高性能，尤其是与基于低密度平等校验验证代码（LDPC）的文献中的最后一个方法相比。特别是，我们证明了我们的方法可以显着改善协议安全性和位错误率（BER），即使具有出色的窃听功能。
In this paper, we propose how to construct a reconciliation method for the BB84 Quantum Key Distribution (QKD) protocol. Theoretically, it is unconditionally secure because it is based on the quantum laws of physics, rather than the assumed computational complexity of mathematical problems. BB84 protocol performances can be reduced by various errors and information leakages such as limited intrinsic efficiency of the protocol, imperfect devices and eavesdropping. The proposed reconciliation method allowed to weed out these errors by using Turbo codes. Since their high error correction capability implies getting low errors, this method has high performance especially when compared to the last method presented in the literature based on Low- Density Parity Check codes (LDPC). In particular, we demonstrate that our method leads to a significant improvement of the protocol security and of the Bit Error Rate (BER) even with great eavesdropping capability.
